Forged Blocks, Rectangles & Flats Manufacturer


Forged Stainless Steel Blocks

Forged steel blocks are created through a manufacturing process that involves the shaping of the forged blocks using localized compressive forces. The forging process begins when a block of steel is compressed within a die. 

Forged steel blocks are considered a raw supply product, even though they have been extensively worked and refined to improve the properties of the metal. The blocks themselves are not a finished product, instead they are used by machine shops and product manufacturers to create a finished part.

Custom Block, Rectangle & Flat Advantages

Forged steel blocks are often preferred to standard plate or bar steel stock straight from the mill due to the inherent advantages that the forging process offers, including greater impact strength.
Stainless steel forged blocks are valued for the enhancements they lend parts for performance in high pressure environments, applications in which corrosion resistance is important, and any application in general that requires greater strength or longer life out of the finished parts.

Some advantages of blocks, rectangles, and flats from Great Lakes Forge include:

  • Quickest lead times in the industry
  • Wide range of stainless, carbon, and alloy steels
  • Milling capabilities that bring product closer to size at reasonable costs
  • Quality controlled heat treating that produce consistent product
  • Testing capabilities to ensure quality and adhere to your requirements
  • Ideal for prototypes and short run situations
  • Produce sizes that aren’t available in plate or bar stock
